A:Answer Hello TonyS,
Yes, the Denon AVR-S970H can output audio from the optical input to Zone 2 while simultaneously using the same HDMI signal in the main zone. If you want to listen to a different source in Zone 2 while having HDMI audio in the main zone, you can only choose from the HEOS, Tuner, USB, or analog inputs for Zone 2. In contrast, the X series receivers can output optical audio in either scenario. Please note that only PCM 2-channel signals will output to Zone 2 in this situation.
Regards,
Denon
